Track diagram for Norlina prior to 1960

I preparing a HO model layout of the Norlina, NC area and would like assistance of the track layout prior to 1960. I would prefer the 1930-40 era, but can use any time frame other than the 1960's. Secondly, does any one know the length of the SAL tressel crossing the Gaston Lake in VA.?

The bridge over Lake Gaston is a garden variety plate girder bridge
with the crossties bolted directly to the plate girders. The last
time I stood on the bridge a couple of years ago, all the crossties
appeared to still be in place.

There's a section in Bill Griffin's book ALL LINES NORTH OF RALEIGH,
a history of the SAL Virginia Division,featuring the Norlina
Subdivision. There are exerts from Timetable No.1, Dec. 19,1943.
There are a couple of photos taken in the '40's, and one from 1902.
You also might try looking at the valuation maps, mentioned in
another question on this site,"Early Depots". Good Luck!

Further regarding my June 9 answer-- in preparation for
a trip to Wise, NC, I purchased a U.S.Geological Survey
map which shows the Lake Gaston trestle. I scaled off
the distance from the north abutment to the south abutment
and it is approximately 2950 feet long -- significantly
shorter than I originally advised. The lake level at the
trestle is 200' above sea level and there is a bench mark
on the south abutment which is 224' above sea level. The
map shows a penninsula extending in a southeastward direction
which is crossed by I-85 and the trestle. The body of water
north of the penninsula is identified as the Roanoke River
and south of the penninsula it's Lake Gaston, so the trestle
actually spans two bodies of water.

Regarding the length of the Lake Gaston trestle -- for lack of a better reference, I consulted SAL's VIRGINIA DIV. TIME TABLE NO. 1
eff. 10/27/63 for any speed restriction between Bracey (Mile Post 86.4) and Paschall (Mile Post 91.3) and find that the maximum speed
for Psgr + Express trains for engine series 3000 + 3100 was 50 MPH
between Mile Post 86.2 and Mile Post 87.1, so it was approximately
nine-tenths of a mile. As I recall it was an innovative design known
as a ballasted deck trestle -- the piling supported a trough that con-
tained ballast so that the track could be laid just as on terra firma.
The advantage was that made-to-order bridge cross ties did not have to
be cut. The disadvantage was that the ballasted deck trestle did not
drain very well.
